Phoenix police on Tuesday said they cracked a 16-year-old homicide case and secured a second-degree murder indictment against a suspect.

Victor Moreno was found shot in a vehicle near Cave Creek Road and Dynamite Boulevard in April 1997. He was 20 years old and left behind a girlfriend and an unborn daughter.

The case stalled for 15 years until 2012 when a group of Phoenix homicide detectives began reviewing Moreno’s killing, officials said. Police eventually linked a friend of Moreno’s, 37-year-old Randall Larson, to the homicide.

Police arrested Larson on Oct. 10, and a grand jury handed up a second-degree murder indictment on Sept. 25.

Police would not say how the trail led investigators to Larson, but credited their success to a combination of forensic investigation and following-up on old information in the case.
